5G NSA is the most suitable solution for 5G early deployment and for complementing NR coverage as full mobility with LTE is supported. As non-standalone mode gradually gives way to new 5G mobile network architecture deployments, careful planning and implementation will make this transition seamless for the user base. 5G NR Radio Protocol Architecture: Scheduling. gNBs can be interconnected through the Xn interface. The 5G architecture introduces a New Radio Access Network (gNB) and Next-Generation Core Network (5GC) to support the diverse range of services specified by 3GPP. Feb, 2019 by Pankaj in 5G, 5G Architecture, NG-RAN Architecture gNB Central Unit (gNB-CU): a logical node hosting RRC, SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that controls the operation of one or more gNB-DUs. Figure 1. Now one of the popular interfaces in 5G RAN is between RU and DU in 5G fronthaul architecture. Although, some types of gNB may connect to the 4G EPC instead of 5G Core. A new use of dual connectivity has also been applied to use LTE/eLTE and NR as the master or secondary radio access technology (RAT) in different combinations. The distributed module gNB-DU supports one or more cells and can only be attached to one central module gNB-CU. Both LTE eNB & NR gNB … 5GPPP Architecture Working Group View on 5G Architecture Version 2.0, December 2017 Date: 2017-12-15 Version: 2.0 Recently (on 20th of December 2017) at Lisbon – Portugal during the 3GPP’s quarterly plenary meeting, announced the completion of first 5G NR specifications. The 5G gNB provides the 5G data path. 5G Fronthaul Architecture | Time Sensitive Networking. The gNB-CU and gNB-DU modules are connected by a logical interface F1. 3GPP 5G architecture Within 3GPP standards, there is a clear functional separation between RAN and 5G core specified as the N1, N2 and N3 reference points. The NG-RAN consists of a set of gNBs connected to the 5GC through the NG interface. Solution Architecture/ ISG Keysight Tony Wang 5G gNB Testing With High-Performance User Equipment Simulation. In Release 15, the 3GPP has defined multiple architectural options for a UE to connect to the network, using LTE/eLTE and/or NR access to connect to Evolved Packet Core (EPC) or 5G Core (5GC) networks. Software Benefits: Compatibility: The Access Software solution can be ported and integrated on any target SoC. 5G Architecture The 5G Radio Network: gNB, AMF, UPF, SMF functions in 5G NR 0 If you are familiar with LTE then it will be easy for you to understand gNB, AMF, UPF, SMF functions in 5G. The 5G NR network composed of NG RAN (Next Generation Radio Access Network) and 5GC (5G Core Network). and finally in 5G we have next generation NodeB, but the short name is gNB. "early Rel-15 drop": focus on architecture option 3, also called non-standalone NR (NSA NR) which could be considered as the first migration step of adding NR base stations (called gNB) to an LTE-Advanced system of LTE base stations (eNB) and an evolved packet core network (EPC) i.e. 5G NG-RAN architecture Source: 3GPP A gNB may consist of a gNB-CU (Central Unit) and one or more gNB-DUs (Distribution Unit). Figure 6.1-1: Overall architecture. A gNB-CU and a gNB-DU is connected via F1 interface. 5G RAN Architecture The 3GPP 5G RAN architecture – specified in Release 15 and known as NG-RAN – introduces new terminology, interfaces and functional modules. Let us turn to the ng-eNB. An gNB can support FDD mode, TDD mode or dual mode operation. 5G NR overall architecture is shown in the following figure-2. The gNB may consist of a Centralized Unit (CU) and one or more Distributed Units (DUs) connected to the CU via Fs-C and Fs-U interfaces for CP and UP respectively. 5G Radio Network Architecture In 5G, the RAN node is referred to as the Next Generation RAN (NG-RAN). 5G architecture is an evolution of current 4G architectures but based on a Service-Based Architecture (SBA). gNBs can be … There are several options available to integrate between different generations of access network technology with the core network. 5G RAN Sharing Architecture 5G RAN Sharing shall follow 4G, which includes MORAN and MOCN features. The architecture also uses the evolved version of 4G-LTE Radio Access Network (eLTE eNB) and Core Network (EPC). gNB Cell Addition Process In NSA Architecture: Step 1: The UE first attaches to the 4G network and signals to the EPC that it supports dual connectivity to 4G and 5G networks (via DCNR bit set to 1 in the attach message).
